 I don't use the other words. I think they're rude, crude, and you can always find a better way to say whatever it is you're going to say. My wife says, oh, biscuits, if she gets upset about something, which I think is something she got from Bluey, because I watched that with my granddaughter. It's a great little show. But we say, oh, biscuits, which works just as well, if all you need is an emphasis word.
